| 摘 要： | 用新育成的带紫叶色标记的水稻不育系先红A(B)为材料,分别与不同类型的绿叶籼稻、粳稻品种杂交,研究其紫叶性状的遗传行为。结果表明,先红A(B)的紫叶性状由1对紫叶基因控制,一般正常绿叶水稻品种带有1～2对抑制基因可调控该紫叶基因的表达。先红A(B)的紫叶性状及其杂种F1绿叶性状表达稳定,不受光温环境及栽培条件的影响。先红A的紫叶性状是杂交稻种子鉴纯和制种防杂保纯的一种理想标记。先红A配制杂种,可筛选出株叶型好且优势强的组合,显示出良好的应用前景。

| Abstract: | In order to study the genetic behavior of the purple-leaf characteristics,a new purple-leaf marker rice CMS line Xianhong A(B) was crossed and backcrossed with different types of indica and japonica lines with normal green leaves.The results showed that the purple leaf color of Xianhong A(B) was controlled by one pair of purple genes,and there were 1 to 2 pair of inhibitory genes could regulate the purple genes expres-sion in normal green color lines.The purple leaf color characteristics of Xianhong A(B) an... |
